So, I admit, it has older BIOS due the fact I have no clue how to flash to newest one.
Its recognize that my Mushkin 2x2Gb 1000 MHz is 800MHz. When I set the ratio so made it 1000MHz, my pc just won't boot. So maximum overclock I can get is 400FSBx9.5=3800MHz, there is no way to go for 401 FSB it just doesnt start ;( even if I downclock RAM. I'm getting Corsair H60 and I'm afraid I wont ever be able to hit 4.5GHz ;(, I need serious help.Edited by Shame486 - 5/29/11 at 2:08pm
